        If you've written a NON-flasher image on the SD card, and it still
tries to run the flasher, you've got a strange eMMC configuration. Try
holding down the boot-select button to force the card to load u-Boot from
SD card (I believe for some years now u-Boot on eMMC is configured to
detect an SD card and then transfer to it to complete booting, but that
implies it is not using the SD card u-Boot)

        If the boot-select with a non-flasher image works, you should be able
to mount the eMMC and explore it for incorrect configuration files. Or zero
it out so it can't boot from eMMC (and maybe eventually reflash it with a
known working image -- convert the working SD card to flasher).
